[0025] The present invention will be further described in detail below in conjunction with the drawings and embodiments.
[0026] Such as Figure 3 to Figure 5 As shown, the rail vehicle side wall integrated molding method of the present invention is to obtain the integrated structure side after high temperature curing of the sandwich structure composed of the outer skin 2-1, the inner skin 2-3, and the foam core material 2-2. Wall 2 method. During the manufacturing process, the outer skin 2-1 and the inner skin 2-3 in the peripheral flanging area of the integrated structure side wall 2 are directly connected to facilitate the assembly of the major components of the rail vehicle body structure.
[0027] The integrated forming method of the rail vehicle side wall of the present invention includes the following steps:
[0028] The first step is to make the corresponding mold 3 according to the outer contour structure of the side wall 2 as the ply and forming foundation of the side ...
